Interprobe
We depended on their capabilities and appreciated their reliability and fairness for more than 20 years. After more than 50 years of heading one of the first and most recognized P.I. Firms in the Washington, D.C. Metro area, without reservation I can say that INTERPROBE was our first choice for contract surveillance and technical investigative services.

I consider INTERPROBE my east coast 'office.' They have been an asset for surveillance and technical countermeasures for our firm for more than 15 years. Their support on cross-national cases and assignments unique to the Washington, DC area is highly valued. They made a case against my client and I decided I better get them on my side for the future.

I contacted this agency concerning an international, crypto currency fraud scheme. After a good consultation with Kevin, he discussed it with their digital investigations team and decided that I would be better served by an expert in Crypto Currency Fraud and tracking. They spoke with several such colleagues and provided me with solid referrals, domestic and international. An ethical and professional outfit.

I hired INTERPROBE to help locate a lost friend from almost 40 years ago who I met while stationed overseas. I had a common name and approximate age but not much else. They located her in a few days and provided full contact information. They were very fair with me and I highly recommend them.

I am very pleased with the quick and professional handling of my case. I was in a difficult situation developing over the weekend that needed fast attention and being overseas made it especially concerning that I would not only find a competent agency but a trustworthy one as well. I am happy to have found this company and I highly recommend them to anyone in need of a really good private investigation service.

Where do I begin. I was referred to Interprobe a few years ago by a good friend. I needed some assistance with a fraudulent trucking deal that span over 4 years in tracking down in 4 states. Interprobe was instrumental in locating 4 individuals, process serving each individual in different states and helping me put together the necessary information for the FBI, US District Attorney and SBA. This information led to a recent 17.5 year conviction. I am very thankful for Interprobe services and the work they performed for me. They were very professional, responsive and fair in pricing for all of the

Thank you all for everything. I cannot say enough good things about Interprobe; not just for the professionalism but skill, guidance and emotional support in what has been a very difficult journey. I would recommend Interprobe to anyone looking for investigative services.

When I suspected the very worst was happening, I needed someone in my corner to help me confirm it so that I could make some decisions. Hiring Kevin and his team was the best decision I made. From our very first phone call, Kevin was professional and efficient but compassionate. I was kept abreast of progress in the case and billing was clear. If you need these services, I highly recommend Interprobe.

INTERPROBE was recommended by my attorney. They did a superb job of surveillance work for me. My case was especially difficult because of the preexisting suspicions of the people involved, but this group got it done.
Further, Kevin is the consummate professional and provided me significant support as I traversed this difficult life changing event. Kevin kept me balanced and focused and for that I am forever thankful for his support!

I had an extended and challenging civil case that ultimately did not settle and went to court. The surveillance team was there the whole way through. They documented the evidence I needed efficiently and two professional investigators were there the day of court to present the evidence and provide expert testimony. Everyone at Interprobe has been exceptionally professional. In the end I prevailed in the case. Without the evidence Interprobe collected I would not have had such a successful conclusion in my case.

I give this company 1 star because during the initial call to this company they listen to my request and forward me to the pi whom could help me but never returned my call for service.

Did not understand there reply due to never getting anyone to answer there phone or return my call. Over all this is not the way to do business or customer service.

Words cannot describe how shocked and completely satisfied I am with Interprobe Investigative Services. "Shocked" at how fast they located someone for me. (I think it was within hours, after MANY attempts, in many years...by many attorneys, and other similar services) "Completely satisfied" by the absolute pleasantness, personal attentiveness, ease of actually reaching, talking or e mailing for quick questions and answers, and lastly, the utmost professional feeling I had throughout, from Kevin and his team, at Interprobe. Wow! (is a word that sums it up quickly)

Kevin and his Interprobe staff were extremely helpful in my case. They reviewed my options step by step and provided information to help me from over spending. They were very responsive and efficient in uncovering the details to my case. I would definitely not only recommend them but use them again.
